Abstract

Local increases in cortical oxygen consumption can be induced by a number of stimuli. These changes are associated with local increases in blood flow which appear to be so finely regulated spatially and temporally that no fall in local oxygen tension occurs (Rosenthal and Jöbsis, 1971; Leniger-Follert, 1980). However, it is very difficult to conceive of a biological response which does not involve an “error” signal. A change of oxygen tension might occur in an area of cortex different than the expected one.
